I used the last two days to automatically generate TypeScript definitions for eslint config and I think I have successfully implemented it 🚀

Just wanted to tell you, so you

1. know that this exists now ^^
2. may spread this plugin a bit

All rules for eslint, @typescript-eslint/eslint-plugin, eslint-plugin-jsdoc, eslint-plugin-unicorn and eslint-plugin-vue are now fully supported!
